The San Diego Chargers are expected to add veteran depth to their defensive line, and free-agent DL Justin Bannan (Broncos) is among the free agents the team has expressed interest in adding to its rotation, according to a source familiar with the situation.

Denver Broncos impending free-agent DTs Justin Bannan and Kevin Vickerson could test the free-agent market to see what kind of deal they can get from other teams. The Broncos are interested in re-signing both players but likely only to short-term deals.
